关于客户
Kifi is an innovative Silicon Valley startup that is revolutionizing the way people search the Internet and store or share information. The platform allows users to easily keep and tag anything they find online, such as articles, videos, pictures, and emails, and quickly find it on top of their favorite search engine results. Kifi also surfaces relevant results that friends have kept, adding a social layer to the search experience. The platform includes messaging to friends, highlighting, and annotation of information found on pages. Kifi's search infrastructure enables users to tag and organize information like a bookmarking system, making it a critical tool for managing online content.
挑战
Kifi CTO and co-founder Eishay Smith faced a significant challenge in building an application capable of performing multiple computationally intensive tasks within a limited time frame. The architecture needed to support high performance at all scales and be flexible enough to scale up and down instantly to meet unpredictable customer usage patterns. Kifi required blazing fast response times throughout the application tiers, robust support for multithreading to maintain performance, and support for rapid continuous deployments. Additionally, the application needed to achieve near-zero downtime and 100% resilience in case of server faults. A strong Service Oriented Architecture (SOA) orientation in the underlying software languages and frameworks was also critical.
解决方案
The Kifi team chose to build their application using the Typesafe stack, leveraging Scala and Play for all web services. The AngularJS website, browser extensions, and mobile clients communicate with the Play API using JSON. Kifi uses Play's native WebSockets capability for low-latency, two-way client communication, enabling real-time messaging and updates. The backend is built with several MySQL databases and a multi-caching layer using Memcached and a custom in-memory cache to improve response times. Kifi's search engine, developed using Lucene components, returns highly personal results, while a custom Graph engine built in Scala generates user recommendations. For distributed work and task scheduling, Kifi uses Typesafe’s Akka, and service coordination is managed with Zookeeper. The Kifi Engineering team actively contributes to the Scala and Play community, fostering a strong ecosystem around these technologies.

Sawback IT and Datto Save Client From a Costly Mistake
Ballistic Echo, a software development house, faced a critical challenge when human error led to the deletion of thousands of lines of unique code. This incident occurred before the code was pushed to source control, resulting in significant loss of time, revenue, and work. The previous file-level backup solution they used was slow and inefficient, making it nearly impossible to manually recreate the lost work. The need for a more reliable and efficient business continuity solution became evident to avoid such disasters in the future.

Opal Helps Customers Shine Thanks to Datto
SP Flooring & Design Center faced a ransomware attack that encrypted and locked their files. The attack was initiated through a compromised service account set up by an outside vendor. The ransomware infection was isolated quickly, but there was a concern about the extent of the data at risk. The company had backups in place but was unsure of how much information was compromised. The situation required immediate action to prevent further damage and restore the affected data.

Zapier Aggregates Multiple Analytics in a Single Dashboard with the New Relic Platform
Zapier, a company that enables non-technical users to push data between hundreds of web applications, was facing a challenge in automating and provisioning servers for optimal performance. The company's environment consisted of 50 Linux servers on the Amazon Elastic Compute Cloud (EC2), a Django application split across several servers, and a backend consisting of a dynamic number of celery task workers fed by messages published to a RabbitMQ cluster. They also maintained a number of internal web services on nginx in front of Gunicorn and Node.js processes. Redis handled simple key and value stores, with logging handled by Graylog2 and ElasticSearch. However, they realized that no level of automation would be sufficient without an effective monitoring solution in place. They needed a tool that could provide immediate alerts when something was breaking and could be easily implemented into their environment.

Pipeline Insight Case Study: YARCDATA
YarcData faced challenges in determining the conversion rates of prospects into customers through various marketing efforts and identifying the source of its leads. They wanted to know the percentage of opportunities in the sales pipeline that came from different marketing events, web downloads, or self-sourced sales opportunities. Additionally, they needed the ability to drill down into the data to guide where to allocate more marketing dollars based on the success of previous efforts. Previously, YarcData relied heavily on spreadsheets and Salesforce.com reports, which made it difficult to extract the exact information they needed. This reliance on spreadsheets represented about 70% of their data presentation.
